Supporting XMPP Standard Foundation's open letter to Meta for true interop

The XMPP Standards Foundation (XSF) has published an open letter to Meta, asking them to support true messaging interoperability using the XMPP protocol.

Meta had previously integrated this protocol, and WhatsApp was actually built on an XMPP-based server, and Meta has previously supported XMPP in Facebook Messenger, as explained in XSF's technical briefing:

A Call to Meta: Build Your Interoperability Stack on XMPP

We at the XMPP Standards Foundation (XSF) urge Meta to build its interoperability framework on top of XMPP federation.

If Threads can implement the Fediverse protocol, there is no reason why Meta cannot do the same with XMPP for Facebook Messenger and WhatsApp—especially since WhatsApp itself was originally built on XMPP.

Why This Matters

We support this initiative as it represents the best approach for genuine interoperability. The European Digital Markets Act (DMA) is specifically designed to break down walled gardens and enforce messaging interoperability across platforms.

XMPP has played a crucial role in shaping the modern messaging landscape, and its success demonstrates that true interoperability is achievable across different platforms and services. It remains the most viable and battle-tested solution to meet interoperability requirements.

As a free and open standard for building and deploying instant messaging systems, XMPP represents the ideal foundation for true messaging interoperability.

Take Action to #FederateTheWorld

Federation is the way to go! Learn more by reading the announcement on the XSF website, where they provide both the open letter and a detailed technical briefing explaining the reasoning behind this call to action.

The XSF, as well as ProcessOne as a long time supporter, is ready to collaborate with Meta and continue to evolve the protocol to meet modern messaging needs.
